FIELD OF THE INVENTION

The field of the invention is collapsible furniture and a wrap for the collapsible furniture.

BACKGROUND

Folding chairs are relatively popular, in part because they can be stored at considerably reduced space requirements when compared to non-folding chairs. Exemplary folding chairs with solid arm rests and seat support rods are described in U.S. Pat. No. 4,613,185 to Marchesini et al. (Sep. 23, 1986), U.S. Pat. No. 5,899,525 to Tseng (May 4, 1999), U.S. Pat. No. 5,947,553 to Tseng (Sep. 7, 1999), and U.S. Pat. No. 6,062,639 to Hill (May 16, 2000), all of which are incorporated by reference herein.

Nevertheless, previously known folding chairs still take up a relatively large space when folded since the dimension of the folding chair is generally reduced only along one space coordinate (e.g., reduced length). To further reduce the space requirement, collapsible chairs have been developed in which further size reduction is achieved by folding the chair along at least two space coordinates (e.g., length and width). Various collapsing chairs are known in the art.

In U.S. Pat. No. Des 247,618 (Mar. 28, 1978), for example, Sparkes describes a collapsible stroller with solid armrests and seat support rods that are first folded in a front to back motion and then folded in a side-to-side motion. Although the Sparkes' stroller provides substantial space saving over non-collapsible strollers, the collapsing is relatively cumbersome since both halves of the chair have to be rotated relative to each other. Improved collapsibility can be achieved by including a detachable connector element into a structure that couples foldable halves of the stroller as described in U.S. Pat. No. 4,317,581 to Kassai (Mar. 2, 1982). Uncoupling of the detachable element advantageously simplifies side-to-side folding of the stroller. However, Kassai's stroller nevertheless requires at least two folding operations to collapse the stroller.

To avoid at least some of the problems associated with multiple operations of collapsible chairs, Mann describes in U.S. Pat. No. 5,058,950 (Oct. 22, 1991) the use of hinges in both armrests and seat support rods. Mann's chair can be collapsed in a single side-to-side and front-to-back motion, however, the hinges in the armrests may be uncomfortable for at least some of the users. Moreover, due to the particular configuration of movable elements in the chair, front and back seat support rods are perpendicular to the legs of a person sitting in the chair, which will likely restrict blood flow in the legs of almost all users over a prolonged period.

None of the documents describe a wrap which is capable of carrying a collapsible chair which may be known as a quad chair.

DETAILED DESCRIPTION

The quad chair wrap (which may be referred to as Victor's Wrap) of the present invention is to provide ease in storage and carrying a quad chair and provides recreational and or advertising functions. The wrap may be made from durable fabric and may be rectangular in shape. The quad chair wrap may be available in different sizes which may depend on the size of the quad chair. Several different attachment materials could be used on the quad chair wrap. For example, hook and loop material (Velcro) may be used for attaching the quad chair wrap to the chair as well as securing the wrap around the folded quad chair. This material may be used in the form of layers in order to provide versatility by being able to apply hook material to one side of the The present invention solves the problem of transporting a chair or example a collapsible chair/quad chair to sporting or recreational event. The present invention provides advantages over placing the chair in an oversized bag in order to be transported and provides a way of sending and message or advertising. FIG. 10 and FIG. 11 illustrates indicia 302 which may be a banner to display a logo or example for a company, a team or other appropriate organization while the folding chair 100 is in use. In addition, the folding chair carrying device 200 holds the chair 100 together in its folded contained position.

FIG. 1 illustrates a collapsible chair/quad chair which may include a pair of front legs, a pair of rear legs, and a pair of solid arm rests. The collapsible chair may further include a backrest and a first cross brace coupled to the front legs, a seat and a second cross brace coupled to the rear legs. The solid armrest may be slidably coupled to at least one of the front legs, the rear legs, the first cross brace, and the second cross brace, such that the chair collapses in a single movement in which the front legs approximate each other when the front legs and the rear legs pivot towards each other.

The collapsible chair 100 may include a pair of front legs 110 (only one front leg shown), a pair of rear legs 120 (only one rear leg shown), and a pair of solid arm rests 130. A first cross brace 140 is coupled to the front legs, and a second cross brace 150 is coupled to the rear legs. A tensioned seat 160 is coupled to the rear legs, and a back rest 170 may be coupled to the front legs, wherein the tensioned seat 160 and the back rest 170 are coupled to each other to form a continuous supporting surface.

A preferred manner of coupling the solid armrest, the front legs, the rear legs, and the cross braces is depicted in FIG. 2, which is a detail view of the chair of FIG. 1. Here, each front leg 210 may be rotatably coupled to a rear leg 220, and a pair of first cross braces 240 may couple the front legs to the rear legs (on the laterally opposing sides of the chair. Each of the first cross braces may be rotatably coupled to a lower portion of a front leg, and rotatably and may be slidably coupled to a rear leg (on a frontal side of the chair). A second pair of cross braces 250 may couple the rear legs to the front legs (on the laterally opposing sides of the chair). Each of the second cross braces may be rotatably coupled to a lower portion of a rear leg, and may be rotatably and slidably coupled to a front leg (on a rear side of the chair). Thus, the front legs and the rear legs may be coupled to each other via the first and second pairs of cross braces to form a quad. Each of the arcuate solid arm rests 230 may be coupled to the respective front and rear legs via a first and a second arm rest support, 232 and 234, respectively. The first arm rest support 232 may be rotatably coupled to the front leg, and the second arm rest support 234 may be coupled to the rear leg. The first armrest support 232 may slidingly engage with the solid armrest, while the second armrest support rotatably may retain the solid armrest in a fixed position.

The seat and the backrest may be fabricated from a weather resistant material or fabric, preferably a woven synthetic polymer (e.g., Nylon) and is uniformly colored (e.g., blue). However, it should be appreciated that various alternative materials, colors, and sizes are also appropriate.
